SUMMARY: In accordance with the Record of Decision (ROD) for the Ukiah Field Office Approved Resource Management Plan (RMP), the Bureau of Land Management (BLM) is establishing final supplementary rules. The Final Environmental Impact Statement (EIS) identified and thoroughly analyzed the effects of land use limitations and restrictions, and specified that supplementary rules would be required for resource protection and visitor safety. Upon publication, these final supplementary rules will supersede the interim final supplementary rules that apply to public lands within the Ukiah Field Office's jurisdiction. The BLM has determined that these final supplementary rules are necessary to enhance visitor safety, protect natural resources, improve recreation opportunities, and protect public health. These rules do not impose or implement any land use limitations and restrictions other than those included within the Ukiah RMP.

DATES: The final supplementary rules are effective February 13, 2013.

ADDRESSES: Bureau of Land Management, Ukiah Field Office, 2550 North State Street, Ukiah, CA 95482. The final supplementary rules are available for inspection at the Ukiah Field Office and on the Ukiah Field Office Web page (http://www.blm.gov/ca/st/en/fo/ukiah.html).
